Now, I didn't stuff the cupcakes with the PB frosting, I think that might have been too much. And I probably should have added a bit more cream to the frosting, it was very thick....but it ended up working!

Chocolate Cupcakes:

made about 16 cupcakes for me

1 1/8 cups all purpose flour

1/4 cup dark cocoa powder

1 1/4 teaspoon baking soda

1/2 teaspoon salt

3/4 cup brown sugar

1 egg

1 teaspoon vanilla extract

1/2 cup milk

1/2 cup + 1 tablespoon heavy cream

1/2 cup butter, melted

2 tablespoons sour cream

1/4 cup homemade fudge sauce (recipe below)

Preheat oven to 350 degrees.

In a bowl, whisk egg and sugar until smooth and no lumps remain.

Add milk, cream, butter and vanilla, and mix until combined.

Stir in sour cream.

Sift dry ingredients together and add to wet mixture.

Mix until batter is smooth, then swirl in fudge sauce.

Line a muffin tin with liners and using a 1/4 cup measure, add batter to each cup.
